COTTON-CHOPPE-R.

SPECIFICATION forming part of Letters Patent No. 376,294, dated January 10, 1888.

Application tiled Novembrr 4, 1887. Serial No. 254,267. (No model.)

To all whom it 11mg/ concern:

Be it known that I, WILLIAM P. CLARK, of Elberton, in the county of Elbert and State of Georgia, have invented a new and useful Improvement in Cotton-Choppers, of which the following is a specification.

My invention relates to improvements in cotton-choppers; and it consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

Figure 1 isa side elevation of my improvement. Figs. 2 and 3 are perspective views of one Of the hangers and pivoted bracket, respeotively.

' Similar letters of reference indicate corresponding parts in all the gures.

Referring to the drawings by letter, A rep- 'Io the sides of the beam A are secured the hangers b, in which the axle c of the Wheel C is `journaled. The axle c is provided at one end with a bevel gear-wheel, d, which meshes with the bevel gear-wheel e on the shaft f. The shaft 2 5 fis journaled in the laterally-projecting armb on one of the hangers b, and in the downwardly-projecting and weighted arm vg of the bracket g, pivoted to the rear end of the beam A'. On the shaft fare rigidly secured'th'e cutters or knives h, so as to be revolved with said shaft. To the rearWardly-projecting arm g2 of the bracket g is pivoted the lower end of the rod 2'., which extends up along one of the handles a, and is engaged by a catch, k, thereon, so that it will be held in the position to which it has been moved.

From the above-described construction it will be seen that as the wheel C revolves, the shaftf and its knives h will also be revolved. In order to throw the'bevel gear-wheel e of the shaftf out of gear with the bevel gearwheel d on the axle, and thus stop the shaftf without stopping the machine, the rod t' is pulled upward, when the bracket g willV be turned upon its pivot, and the shaft f and its gear-wheel e moved endwise to the'position shown in dotted lines, thereby throwing the said gear-wheels out of gear. When it is desired to start the shaft f and its knives h, it will only be necessary to disengage the rod i from the catch 7., when the shaftj will be moved forward by the weighted arm g' of the bracket g, and the gear-wheel e made to mesh vwith the gear-wheel al. f

@It will be noticed that in order to permit of this endwise movement of the shaftf, thejournals of the said shaft are elongated to permit them to slide in their bearings.

Plows Z, for throwingsoil to the plants, may be secured to the rear of the plow'beam A.

Having thus described my invention, what I claim, and desireto secure by Letters Patent, Is Y l. VIn a cotton-chopper, the combination, with a beam, a drive-wheel, and a bevel gear wheel on the end of its axle, of an angular bracket pivoted to the rear end of the beam, a shaft having one end Vjournaled in the said bracket and its other end in a Xed bearing, a bevelwheel on one end of the shaft, knives or cutters on the said shaft, and means'for Vturning the said bracket on its pivot to move the shaft longitudinally, as and for the purpose set forth.

2. In a cottonchopper, the combination, with the beam A. and the hangers b, one of which is provided with the arm b,of the wheel C, the bevel gear-wheel d on the end of its axle, the bracket g, pivoted to the rear end ot' the beam, the shaftj, journaled in the arm b', and bracket g, the knives 7L on the shaftf, the rod i, pivoted to the arm g2 ofthe said bracket, and catch lr, for engaging the rod, substantially as herein shown and described.

WILLIAM P. CLARK.
